Exception when declaring class with generic base type

[adrianoc]

We should also test at least base types:

• [ ] List<T> (generic external type)
• [ ] Generic types with .ctors

class Bar<T> {}

class Foo : Bar<int>
{
    void Baz() => System.Console.WriteLine("Hello World!");
}

System.NullReferenceException: Object reference not set to an instance of an object.
